The Goodman 20165703S is the OEM hot surface ignitor (HSI) for the WFD18045S3AXCB furnace and compatible Goodman/Amana gas furnaces. On each heat call the control board energizes this ignitor, which glows white-hot to light the main burners — making it one of the most common wear items in the entire furnace.

This ignitor uses a rugged silicon-nitride element that resists the thermal shock and cracking that plague older carbide-style igniters, delivering longer service life and more reliable cold-morning starts. A no-heat, no-glow condition is the classic symptom of a failed HSI.

OEM vs. Generic

The OEM 20165703S arrives with the correct connector, bracket, and element resistance so it plugs in without adapters. Universal igniter kits require harness splicing and often use less durable elements. For dependable ignition and easy installation, OEM wins.

Installation Difficulty

Moderate (3/5). Involves accessing the burner compartment, unplugging the connector, and unscrewing the bracket. Handle the fragile element by the bracket only. About 30 minutes; power off before servicing.
